Description

When writing to an index beyond the last index written to, Variable Length vectors set the 'empties' by writing a zero length byte array to the indexes that were skipped.

This is, as it turns out, sometimes an expensive operation, and is completely unnecessary as all that needs to be done is to set the offset vector correctly.
